OpenGL is not used for movie rendering at all, that industry is dominated by software rendering because of quality issues. This may change soon with hardware accelerated rendering now that the programmability and precision is there to support it, maybe not.
All of the tools and software used to produce 3D effects for films of all sorts use OpenGL. This is almost entirely without exception. OpenGL dominates the movie industry despite the rendering being done in software.

Well, roffe, what he said is interesting, but I would like to say that’s not the reason why OGL is not used for CGI rendering. And what is interesting too is to know that compositing and special FX software are not using the GPU advanced shading features that should drastically enhance rendering speed and visual quality… You must know that for some of particle or warping based special effects OGL is used as renderer.
Sure, computer graphics is a wide world : I think to know what people have globally thinked, have a look and learn Alias Wavefront, Adobe and Descreet products, use it in production, and you’ll have a good vision of all CGI algorythms.
